The figure for the problem statement is given as,
From the above figure,
[tex]\begin{gathered} \theta_1\text{ + }\theta_2\text{ = 130 }_{}\text{ \_\_\_\_\_\_\_\_(1)} \\ 18\cos \theta_1\text{ = 30 cos}\theta_2\text{ \_\_\_\_\_\_(2)} \end{gathered}[/tex]
Also,
[tex]d=\text{ 18sin}\theta_1\text{ + 30sin}\theta_2\text{ \_\_\_\_\_\_\_(3)}[/tex]
From equation ( 1 ) and ( 2 ) ,
[tex]undefined[/tex]
